MAX4474ESA Equivalent & Substitute Parts Reference

Part Overview

The MAX4474ESA is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, configured as a dual-channel (2 circuit) rail-to-rail amplifier in an 8-SOIC surface mount package. This device is classified as obsolete, which necessitates identification of active equivalent and substitute components for new designs and production continuity.

The MAX4474ESA operates across a supply voltage range of 1.8 V to 5.5 V with an operating temperature range of -40°C to 85°C. Its primary application domain includes low-power, general-purpose amplification circuits where rail-to-rail output capability is required. The obsolete status of this component makes substitute part identification critical for design engineers and procurement specialists.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4474ESA is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Dual-channel (2 circuit) configuration
• Rail-to-rail output capability
• 8-SOIC surface mount package (0.154", 3.90mm width)
• Supply voltage range compatibility: minimum 1.8 V, maximum 5.5 V
• Operating temperature range: -40°C to 85°C (or extended range)
• ROHS3 compliance and MSL rating

Secondary Compatibility Parameters:

• Input bias current (200 pA baseline)
• Input offset voltage (500 µV baseline)
• Supply current per channel (750 nA baseline)
• Output current per channel (36 mA baseline)
• Slew rate (0.02 V/µs baseline)
• Gain bandwidth product (40 kHz baseline)

Substitute parts are grouped into two categories:

Category 1: Direct Functional Equivalents — Parts that maintain identical or near-identical electrical specifications and can serve as pin-compatible replacements with minimal circuit redesign.

Category 2: Enhanced Performance Alternatives — Parts that exceed baseline specifications in one or more parameters (higher slew rate, higher gain bandwidth product, lower supply current, extended temperature range) while maintaining package compatibility and core functionality.

Parameter Comparison

Engineering Selection Recommendations

Tier 1: Direct Replacement (Identical Specifications)

MAX4474ESA+ is the primary direct replacement. This part is manufactured by the same supplier (Analog Devices Inc./Maxim Integrated) and maintains identical electrical specifications across all measured parameters. The only difference is product status (Active vs. Obsolete) and packaging format (Tube). This part is suitable for direct substitution without circuit modification. ROHS3 compliance and MSL rating are maintained.

Tier 2: Compatible Substitutes (Package and Supply Voltage Compatible)

OPA2349UA/2K5 (Texas Instruments) maintains 8-SOIC package compatibility and identical supply voltage range (1.8 V to 5.5 V). However, this part operates at a reduced maximum temperature of 70°C (versus 85°C for the MAX4474ESA). This part is ROHS3 compliant and suitable for applications where the temperature limit is acceptable. The part is currently in active production status.

RE46C312S8F (Microchip Technology) maintains 8-SOIC package compatibility and supply voltage range. However, this part has a reduced operating temperature range (-10°C to 60°C), which is narrower than the MAX4474ESA specification. This part is suitable only for applications within this temperature window. Product status is Active with ROHS3 compliance.

Tier 3: Enhanced Performance Alternatives (Improved Specifications)

NCV20032DR2G and NCS20032DR2G (onsemi) both provide 8-SOIC package compatibility with extended operating temperature range (-40°C to 125°C). These parts feature significantly improved slew rate (8 V/µs) and gain bandwidth product (7 MHz), making them suitable for higher-speed applications. Supply voltage range is compatible (1.7 V to 5.5 V). Both parts are in active production status with ROHS3 compliance.

TLV342AIDR (Texas Instruments) provides 8-SOIC package compatibility with extended operating temperature range (-40°C to 125°C) and improved slew rate (1 V/µs) and gain bandwidth product (2.3 MHz). This part is in active production status with ROHS3 compliance and is suitable for applications requiring enhanced performance within the extended temperature range.

Tier 4: Package Variant (Not Recommended for Direct Substitution)

LMR932F-GE2 (Rohm Semiconductor) uses an 8-SOP package (0.173", 4.40mm width) rather than the 8-SOIC package of the MAX4474ESA. While electrical specifications are compatible, the different package footprint requires PCB redesign. This part is suitable only when PCB layout modification is feasible.

Compliance and Certification Status

All recommended substitute parts maintain ROHS3 compliance. Moisture sensitivity levels are consistent with the original part (MSL 1 or MSL 2). All parts carry EAR99 export classification and are subject to the same HTSUS tariff code (8542.33.0001) as the original component.

Frequently Asked Questions (FAQ)

Q1: Can MAX4474ESA+ be used as a direct replacement for MAX4474ESA?

A: Yes. MAX4474ESA+ is manufactured by the same supplier and maintains identical electrical specifications. The only differences are product status (Active vs. Obsolete) and packaging format (Tube vs. standard). No circuit modification is required. Both parts are ROHS3 compliant with MSL rating 1.

Q2: What is the primary reason to substitute the MAX4474ESA?

A: The MAX4474ESA is classified as obsolete, meaning it is no longer in active production. Substitution is necessary to ensure long-term design continuity, supply chain reliability, and compliance with current manufacturing standards. Active alternatives ensure availability for new production runs and future design iterations.

Q3: Are there performance differences between the MAX4474ESA and the onsemi NCV20032DR2G?

A: Yes. The NCV20032DR2G provides significantly enhanced performance: slew rate of 8 V/µs (versus 0.02 V/µs), gain bandwidth product of 7 MHz (versus 40 kHz), and extended operating temperature range to 125°C (versus 85°C). These improvements make it suitable for higher-speed signal processing applications. However, supply current is higher (275 µA versus 750 nA per channel). Package compatibility (8-SOIC) is maintained.

Q4: Which substitute part is best for low-power applications?

A: OPA2349UA/2K5 (Texas Instruments) offers the lowest supply current at 1 µA per channel, compared to 750 nA for the MAX4474ESA. However, this part has a reduced maximum operating temperature of 70°C. For applications requiring both low power and the full -40°C to 85°C temperature range, the MAX4474ESA+ remains the optimal choice.

Q5: Can I use TLV342AIDR in place of MAX4474ESA without PCB modification?

A: Yes. The TLV342AIDR uses the same 8-SOIC package (0.154", 3.90mm width) and maintains pin compatibility. However, electrical specifications differ significantly: slew rate is 1 V/µs (versus 0.02 V/µs), and gain bandwidth product is 2.3 MHz (versus 40 kHz). Circuit performance will change. Verification of circuit behavior is necessary before production implementation.

Q6: What is the difference between NCV20032DR2G and NCS20032DR2G?

A: Both parts are manufactured by onsemi and share identical electrical specifications except for output current per channel: NCV20032DR2G provides 14 mA, while NCS20032DR2G provides 96 mA. Selection depends on output current requirements. Both use 8-SOIC packaging and are ROHS3 compliant.

Q7: Is LMR932F-GE2 suitable for direct PCB substitution?

A: No. LMR932F-GE2 uses an 8-SOP package (0.173", 4.40mm width) instead of the 8-SOIC package (0.154", 3.90mm width) of the MAX4474ESA. The different package footprint requires PCB layout redesign. This part is suitable only when PCB modification is feasible and acceptable.

Q8: Which substitute parts maintain the full -40°C to 85°C operating temperature range?

A: MAX4474ESA+ and LMR932F-GE2 maintain the identical -40°C to 85°C range. All other substitutes either reduce the maximum temperature (OPA2349UA/2K5 to 70°C, RE46C312S8F to 60°C) or extend it (NCV20032DR2G, NCS20032DR2G, TLV342 variants to 125°C).

Q9: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain ROHS3 compliance, consistent with the original MAX4474ESA specification. Moisture sensitivity levels are either MSL 1 (unlimited) or MSL 2 (1 year), both acceptable for standard handling and storage.

Q10: What packaging options are available for MAX4474ESA substitutes?

A: Most substitutes are available in 8-SOIC packaging (0.154", 3.90mm width), which is pin-compatible with the original part. LMR932F-GE2 is available in 8-SOP packaging (0.173", 4.40mm width), which requires PCB redesign. Packaging formats include Tube, Cut Tape (CT) & Digi-Reel®, and Tape & Reel (TR) options depending on the specific part number variant.
